Hi Maurice,

I think it is subtended that Cirilo was comparing that with original FreeCAD VRML exporter, so I see nothing wrong with that and it does not do in any way an attack competition to your StepUP converter.
Looks like Cirilo is trying to develop a 3d plugin for KiCad, this is a different process and it is ok to have different processes and they all coexist.

Maybe you can propose a STEP file to Cirilo to test instead? So you can both compare your results?
I could also suggest some very small VRML file output so you can share (with me!) and really have a look on its content.

Mario

Subject: Re: [Kicad-developers] 3D models: custom VRML export vs FreeCAD (OCE/Coin3D) VRML export

the problem with your comparison is a wrong way to export from FreeCAD...
if you use kicad in wrong way you could also say kicad is useless for
creating pcbs ...
if you share a STEP model you have made, or just with public license I
will make a comparison with that...
I have many STEP models for a real comparison, I did MCAD libraries for
MCAD collaboration with STEP and VRML models for kicad and they will not
give any warnings, or bad lighting model for VRML .... but that would be
on my point of view :)
I would show you what can be done with FreeCAD and kicad StepUP on your
side :)
